CPS Test

Six run lengths, from a one second reflex burst to a hundred seconds of endurance, and the clock starts on your first click rather than on a start button, so none of the run is spent travelling to the target. Left clicks, taps, the space bar and Enter all count, right clicks are ignored so the context menu cannot interrupt you, and a held key repeats rather than clicking. Beside the average you get your fastest one-second window wherever it fell in the run, and when time is up on any run longer than a second, one bar for each second showing where the pace held and where it faded.

Changing the run length starts again. Press R to reset from anywhere on the page, and the space bar counts as a click while the stage is focused. Speeds are banded plainly: under 5 is slow, 5 to 8 is average, 8 to 10 is fast, 10 or more is very fast.

The timer starts on your first click, not on a start button. A run that begins the moment you press means the first fraction of a second is never wasted reaching for the target, which on a five second run at ten clicks a second is worth about half a click a second. Right clicks are ignored, so the context menu never gets in the way, and a held space bar repeats rather than clicking, so its repeats are not counted either. Nothing is uploaded: the counting happens in this page, and the only things kept are the run length you chose and your best run at each length, in this browser.

Common questions

What is a good CPS score?
This page bands it plainly: under 5 clicks a second is slow, 5 to 8 is average, 8 to 10 is fast, and 10 or more is very fast. The bands do not shift with the run length, so the same number means the same thing whenever you run it, and the run length is where the real difference shows: a one second burst flatters you, because a reflex can be held for a second and not for a hundred, and a hundred second run is a test of stamina rather than speed. Your best is kept separately for each run length for exactly that reason.
Does the space bar count as a click?
Yes. While the dark stage is focused, the space bar and Enter each count as one click, so the test works with no mouse at all. Holding a key down does not: the operating system repeats the key at its own rate, which is the keyboard clicking rather than your hand, and repeats are thrown away. On the mouse only the left button counts. Right clicks are ignored, and the context menu is held back inside the stage so a stray right click cannot cover the run.
Why does the clock start on the first click instead of a start button?
Because the two or three tenths of a second it takes to move to a start button and then back to the target are not clicking, and a timer that starts before that charges you for them. Three tenths of a second lost at ten clicks a second is three clicks, which on a five second run is 9.4 rather than 10.0. Here the first click is both the first thing counted and the moment the clock starts, and the run ends exactly one run length later, measured from that click.
Why is my fastest second higher than my clicks per second?
Because they measure different things. Clicks per second is the whole run divided by its length, so every pause is in it. The fastest second is the best single one-second stretch, and it is found with a window that can start anywhere rather than on a second boundary: six clicks either side of the one second mark is a twelve click second, and counting whole seconds would report that burst as six. On any run past a few seconds the fastest second is almost always the higher figure.
What are jitter clicking and butterfly clicking?
They are two ways of getting more presses out of one finger. Jitter clicking is tensing the arm so the hand vibrates and the finger bounces on the button; butterfly clicking is alternating two fingers on the same button. Both register here, because this tool counts the presses the browser reports and cannot see how they were made. That also means it cannot tell an auto-clicker from a hand, so a number from this page is a measurement of your browser's click events, not proof of anything.
Where is my best score kept?
In this browser, on this device, and nowhere else. The run length you chose, and for each run length your best clicks per second and how many clicks that was, sit in local storage; clearing site data removes them. Nothing is uploaded, there is no account, and the counting and the arithmetic both happen in the page you are looking at.

Clicks are counted from the first one, which also starts the clock, so no time is lost reaching for a start button. Left clicks, taps, the space bar and Enter all count; right clicks do not.
